When joining several data frames, you have an option of how to handle the different axes (other than the one being concatenated). To show you how this can be used, take the union of them all,join='outer'. Consider the intersection withjoin='inner'because it causes no information loss an...
Natural join or Inner Join: To keep only rows that match from the data frames, specify the argument all=FALSE. Full outer join or Outer Join:To keep all rows from both data frames, specify all=TRUE. Left outer join or Left Join:To include all the rows of your data frame x and only...
